| Abstract: | Background and aims: Orexins/hypocretins are orexigenic peptides implicated in the regulation of feedingbehavior and the sleep/wake cycle. Little is known about the functioning of these peptides in anorexianervosa (AN). The aims of the current study were to evaluate the extent to which orexin-A might belinked to sleep and treatment outcome in AN. Method: Fasting plasma orexin-A concentrations were measured in 48 females with AN at the start of a dayhospital treatment and in 98 normaleater/healthy-weight controls. The Pittsburgh Sleep Quality Indexwas administered at the beginning of the treatment as a measure of sleep quality. Other psychopatho-logical variables were evaluated with the Symptom Checklist-Revised (SCL90R) and the Eating DisorderInventory-2 (EDI). Patients were assessed at the start and end of treatment by means of commonly useddiagnostic criteria and clinical questionnaires. Results: The AN patients presented more sleep disturbances and poorer overall sleep quality than didthe healthy controls (p = . 026) but there were no global differences between groups in plasma orexin-Aconcentrations (p = . 071). In the AN sample, orexin-A concentrations were associated with greater sleepdisturbances (|r| = . 30), sleep inefficiency (|r| = . 22) and poorer overall sleep (|r| = . 22). Structural EquationModeling (SEM) showed that both elevated orexin-A concentrations and inadequate sleep predictedpoorer treatment outcome. contribute to poor sleep quality in AN, and both of these variables are associated with therapy response. |
